CHURN.

SPECIFICATION forming part of Letters Patent No. 299,459, dated May 27,1884.

Application filed December 27, 1883.

butter from cream by churning in a short space of time and with a smallamount of labor, and also at the same time to provide a churn thatcombines the perpendicular dash movement with a partial circular motionof -the cream. These objects I attain by means of the device illustratedin the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a side elevation with a part removed to show theentire device. Figs. 2 and 3 are detailed views.

The distinctive features of my invention consist in two heads in and fora churningvessel through which the dashers work; two dasher-heads, eachhaving one or more rows of oblique paddles; a pinion attached to adouble crank or eccentric rod, and operated by a large drive-wheel 5adjustable arms attached to the double eccentric rod and dashers, andother novel features hereinafter more fully set forth.

S is a vessel; A, a cover supported upon and in said vessel. This coverhas two holes near the center for the dasher-rods B B, and also holesfor attaching the posts 0 G O. The lower ends of the said posts arefirmly attached in and support a secondary head, A. These two heads arepreferably placed three or more inches apart, to facilitate cleaning thesame, and to prevent the cream from splashing out when greatly 'agitatedby the twofold motion given by the dashers, as hereinafter explained andfor this purpose the secondary head is made to fit closely the inside ofthe vessel. The upper head is made to fit closely by a groove, a, andflange a, and any suitable device for firmly attaching it to the vessel.Up- 011 this head are rigidly attached uprights R (No model.)

B, for supporting the bearings of a crank-shaft, G, and the attachmentsof the bearings to the drive-wheel D. The crank-shaft G is made with adouble eccentric or'crank, and attached to one end is a small pinion,E,which is operated by a large drive wheel, D, to impart great Velocityto the dashers, the dashers being attached to the crank-shaft G by meansof adjustable arms 0. The arms 0 0 have suitable bearings on thecrank-shaft G, and are made forked at o 0 from a point near the bearingson the shaft to the lower ends, said forks being of sufficient width tofreely-admit the upper ends of the dasher-rods B B. These arms are madeadjustable in length by means of a bolt, 0 which is placed through theend of the dasher-r'ods and up or down in the holes 0 0 0, as desired.These arms, together with the double head A A, cause the dashers to workup and down perfectly true, so that the dasher-heads cannot strikeagainst the sides of the vessel. The primary dash-rod B passes throughthe center of the head I of the secondary dasher, the secondary dash-rodB being attached to one side of thesaid head. The headsI K are eachpreferably made with two rows of paddles, b b k and with four or moreofthe said paddles in each row. These paddles are placed in the headsobliquely, or so as to form an acute angle with the horizontal. Thepaddles are preferably slanted in the same direction in the two rows ofthe head, to start thecream to rotating as they pass through it. As thedasher-heads when in operation move in opposite directions, toward andfrom each other, it ispreferable to place the paddles k k so as to slantin the opposite direction from b b, so as to start the entire mass ofcream to circulating in the same direction as the dashers move from eachother, and then to throw it in the opposite direction as they approacheach other, and thus create a great agitation in the entire mass ofcream, and herein is one of the great advantages of the novelconstruction of my dasher-heads.

By means of the adjustable arms 0 O the dashers are so placed that onewill reach almost to the bottom of the vessel, so as to agitate thecream in the bottom,while the upper head, I, is so adjusted as to riseabove the cream, and then, by its great velocity, strike the creamflowing in one direction and cause it to rapidly flow in the other, andthus thoroughly aerify the same, and produce butter in a very shorttime, while at the same time the double head keeps all the cream in theVessel, and thus it is perfectly clean outside.

Having thus described my invention. what I claim as new, and desire tosecure by Letters Patent, is-

1. In a double-dash churn, the combination of a double head, A A, twodasher-heads, I K, having paddles b bk L placed in two rows in each headand in oblique positions, pinion E, crank-shaft G, drive-wheel D, andadjustable
